Oxidation control at every stage
Omega-3 oxidation is not a single event to be tested for at the end -- it is managed at every stage, from the crude oil intake to the moment the drum is sealed.

Flow diagrams, typical batch data and the control points behind this stage are available on request.
Process information
| Stage | Applied continuously from intake through drum filling |
|---|---|
| Measured by | Peroxide value, anisidine value, TOTOX |
| Grading | Standard ≤ 26; low-TOTOX < 6 on request |
| Records | Oxidation values, antioxidant dose and headspace treatment logged per batch |
Technical detail
| Nitrogen blanketing | Applied to storage, transfer and the drum headspace so the oil is never held under air |
|---|---|
| Antioxidant | Mixed tocopherols as standard, dosed against the declared TOTOX target rather than a fixed amount |
| Temperature | Ambient storage with controlled transfer temperatures; no unnecessary heat cycles |
| Packaging | Epoxy-lined drums, nitrogen flushed and sealed immediately after filling |
Quality control
What is checked before and after this stage.
| Intake | Crude and refined feed oils tested on arrival and rejected if already outside the incoming limit |
|---|---|
| In-process | Holding times capped between stages; the oil is not left exposed while a line is idle |
| Release | PV, AV and TOTOX verified against the customer's declared limit before the COA is issued |
| Retention | Retained samples allow the oxidation trajectory to be re-checked during shelf-life review |
Handling and packaging
| Headspace | Nitrogen, verified at filling |
|---|---|
| Container | 190 kg epoxy-lined steel drum |
| Shelf life | 24 months when kept sealed at ambient temperature |
| Handling note | Opened drums should be used promptly and re-blanketed; see the buyer guidance on opened-drum handling |
How an order runs
State the PV, AV and TOTOX limits your release procedure actually applies.
Standard or low-TOTOX, depending on how sensitive the finished product is.
Agree the antioxidant and dose where the formulation restricts the options.

Nerivanta-Quality-Documentation.pdfFrequently asked questions
What TOTOX values can be supplied?
Standard production targets TOTOX ≤ 26. Low-TOTOX lots held below 6 are produced on request for sensitive formulations.
Does nitrogen blanketing change the specification?
No. It changes the rate at which the oil oxidises after filling, which is why it is applied to storage, transfer and the drum headspace.
How should an opened drum be handled?
Use the contents promptly, minimise headspace exposure, and re-blanket or transfer to a smaller sealed container for the remainder.
